摘要:

Hexagonal close-packed helium crystals in equilibrium with superfluid have been found to be one of the few systems in which an anisotropic solid comes into true thermodynamic equilibrium with its melt. The discovety of roughening transitions at the liquid-solid interface have shown this system to be ideal for the study of the statistical mechanics of interface structures. We describe the effect of roughening on the shape and growth of macroscopic crystals from both the theoretical and experimental points of view.

摘要:

A widespread interest has arisen in recent years in intermetallic compounds which show a variety of unusual properties. Prominent amongst these is a very large electronic contribution to the specific heat at low temperatures which can be parametrized in terms of an effective mass hundreds or thousands of times larger than those in normal metals. The background to this behaviour is outlined and some of the electrical, magnetic and superconducting properties of such materials, mainly alloys of Ce or U, are presented.

摘要:

The inverse square law of gravitation is very well established over the distances of celestial mechanics, while in electrostatics the law has been shown to be followed to very high precision. However, it is only within the last century that any laboratory experiments have been made to test the inverse square law for gravitation, and all but one has been carried out in the last ten years. At the same time, there has been considerable interest in the possibility of deviations from the inverse square law, either because of a possible bearing on unified theories of forces, including gravitation or, most recently, because of a possible additional fifth force of nature. In this article the various lines of evidence for the inverse square law arc summarized, with emphasis upon the recent laboratory experiments.
